Back protective cover for tablet device

ABSTRACT

A back protective cover for a tablet device is provided which is capable of preventing a touch-screen cover from coming off the tablet device. According to the present invention, a back protective cover which covers a back of a tablet device is provided, the back protective cover comprising a separation preventing section configured to cover an attaching/detaching section of a touch-screen cover of a detachable type, the touch-screen cover covering a touch screen of the tablet device, so as to prevent separation between the touch-screen cover and the tablet device.

FIELD OF THE INVENTION

This invention is related to a back protective cover for a tablet device.

BACKGROUND ART

One of the accessories for a tablet device placed on the market by Apple Inc. is a touch-screen cover which can be attached to and detached from the tablet device by means of a built-in magnet and can protect a touch screen of the tablet device. Further, the touch-screen cover functions as a keyboard stand when folded, and thus, is very convenient.

SUMMARY OF THE INVENTION Problems to be Solved by the Invention

The above-mentioned touch-screen cover is very convenient as noted above, however, the inventor of the present invention has found, while using it, that the touch-screen cover sometimes comes off the tablet device when grasping only the touch-screen cover and lifting it. In order to prevent the problem of coming off of the touch-screen cover, making the magnet more powerful or fixing the touch-screen cover to the tablet device with an adhesive or the like might be effective. However, since one of the attractive features of the touch-screen cover is that it can be easily detached when it is not needed, making the touch-screen cover difficult to come off by such methods will detract the attractive feature of the touch-screen cover.

Such a problem arises not only in the combination of the tablet device made by Apple Inc. and the above-mentioned touch-screen cover for this tablet device but also in a combination of a tablet device other than the tablet device made by Apple Inc. and a touch-screen cover attachable to and detachable from this tablet device.

The present invention is made in view of such a circumstance and provides a back protective cover for a tablet device which can prevent a touch-screen cover from coming off the tablet device.

Means to Solve the Problem

According to the present invention, a back protective cover which covers a back of a tablet device is provided, the back protective cover comprising a separation preventing section which is configured to cover an attaching/detaching section of a touch-screen cover of a detachable type, the touch-screen cover covering a touch screen of the tablet device, so as to prevent separation between the touch-screen cover and the tablet device.

While a back protective cover is sometimes attached to a back of a tablet device in order to prevent a casing of the tablet device from being scratched, the inventor of the present invention has found that a problem of coming off of a touch-screen cover can be prevented by using a back protective cover that is provided with a separation preventing section shaped to cover an attaching/detaching section used in attaching the touch-screen cover to the tablet device, and has completed the invention.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows a state in which a back protective cover according to an embodiment of the present invention is attached to a tablet device to which a touch-screen cover has been attached, where (a) is a plan view, (b) is a back view and (c) is a side view.

FIG. 2 is a sectional view taken along line A-A in FIG. 1( a).

FIG. 3 is an enlarged view of region B in FIG. 2.

EMBODIMENTS FOR CARRYING OUT THE INVENTION

Hereafter an embodiment of the present invention will be described with reference to FIGS. 1 to 3. The following embodiment is only for illustrative purposes and the scope of the present invention is not limited to the one illustrated by the following embodiment.

As shown in FIGS. 1 to 3, a touch-screen cover (e.g., “iPad Smart Cover”) 3 is provided on a touch-screen side of a tablet device (e.g., “iPad2”) 1. The touch-screen cover 3 is of a detachable type and comprises a main section 3 a configured to cover a touch screen (not shown) of the tablet device 1 and an attaching/detaching section 3 b configured to allow the touch-screen cover 3 to be detachably attached to the tablet device 1. The attaching/detaching section 3 b has a built-in magnet and the attaching/detaching section 3 b is fixed to a side surface of the tablet device 1 by means of magnetic force. The main section 3 a is rotatable with respect to the attaching/detaching section 3 b at a hinge portion 3 c, so that the main section 3 a can be opened and closed with the attaching/detaching section 3 b fixed to the tablet device 1.

A back protective cover 5 is provided on a back side of the tablet device 1. The back protective cover 5 is of a detachable type and comprises a main section 5 a configured to cover a back surface (and side surfaces) of the tablet device 1 and a separation preventing section 5 b which extends from the main section 5 a. The main section 5 a can be fixed to the tablet device 1. The separation preventing section 5 b is bent so as to surround the attaching/detaching section 3 b and prevents the attaching/detaching section 3 b from being separated from the tablet device 1. Therefore, by using the back protective cover 5 of this embodiment, the touch-screen cover 3 never comes off the tablet device 1 even if only the touch-screen cover 3 is lifted, and thus, the problem of falling of the tablet device 1 or the like can be prevented. Further, in a case of using a back protective cover without the separation preventing section 5 b, a surrounding area of the attaching/detaching section 3 b is exposed so that the tablet device 1 may be scratched in the area, however, by using the back protective cover 5 of this embodiment, which has the separation preventing section 5 b, the surrounding area of the attaching/detaching section 3 b is also covered by the back protective cover 5, and thereby the problem of scratching can be prevented.

The back protective cover 5 is preferably made of polycarbonate. With this material the back protective cover 5 can be transparent, so that a logo and the like provided on the back surface of the tablet device 1 can be visually recognized in a state where the back protective cover 5 is attached.
